Mono Monday - Mysterious...

....place...

Thanks to sk who is hosting the challenge for October.

Edit for further information:  This tiny apartment is one of at least five basement windows in the city, furnished for mice! The first one was created by a cafeteria nine years ago, two are made by an artist, the fourth one is a private idea. The apartment in the photo (the 5th one we know) is definitely a private work, made by two girls, according to the information in the window. I guess they live with their families in the builning and had got a permission to create a home for mice... :)

We had never heard about none of the mouse houses, but thanks to our grandchildren we saw the first one and are nowadays searching for new ones!
